- 2010 April 14: "The mine-resistant ambush-protected
all-terrain vehicle (M-ATV) is on its way to
Afghanistan to replace many of the up-armored Humvees."
-- US Army.
The story of Afghanistan, and Iraq, was the increasing use of
improvised explosive devices (IEDs);
many HMMWVs were "up-armored" but a need was still seen for
a vehicle that was more IED-resistant for use in the more dangerous areas --
- 2010: The US Army took delivery of prototypes of the
(Joint Light Tactical Vehicle) from
BAE-Navistar, General Tactical Vehicles, and Lockheed-BAE,
for competitive tests.
(The Department of Defense Appropriations Act, 2012,
seemed to terminate the JLTV program,
2 Dec 2011,
but it was still active
5 Jan 2012,
and in fact full-scale production was approved
21 June 2019.)
